Alert Details

Moderate western bean cutworm risks continue across the eastern Great Lakes region and also a portion of the Plains, but the overall threat from this insect this growing season is now waning as the primary flight is subsiding and crops advance past critical growth stages. Moderate risks remain in place from central lower Michigan east into southern Ontario and southwest Quebec, Canada where the greatest risk remains in place this week. Additional Moderate risks are in place across northeast Nebraska, northwest Iowa, and southeast South Dakota where replanted fields due to hail/heavy rainfall in early June may still be at susceptible stages to damage and also where some traps continue to catch more than just a few moths a night. Low risks extend from Nebraska and southern South Dakota east into Minnesota, northern Iowa, Wisconsin, lower Michigan, far northern Indiana and Ohio, northwest Pennsylvania and New York, and southern Ontario and Quebec, Canada. Growers located especially in Moderate risk areas are urged to continue to check traps for moths and fields for signs of larvae and egg-laying especially if the crop is at a susceptible stage to damage from this particular insect.
